DJZ's DR30 Skyline

wow looks like you could fit another fj between that one and the firewall lol .looking great though,

Hmm a 4 litre straight 8 FJ, maybe that should be my next project? Haha.

[DJZ]

Made a down pipe today, twice. Wasn't happy with how low the first one was so I made it again, still seems to fit after welding it together which is a bonus. Everything going to plan this should be running again tomorrow. If anybody local had some thing copper sheet I can make a wastegate gasket out of let me know.

Made a little dump pipe for the wastegate but I must be tired, when I got home I realised I've tacked the pipe in the wrong side of the v band flange, whoops. Will fix it at some stage.

I have always had good success with no Gasket on the waste gate flange All I did with mine was surface it on a flat piece of alloy with some 600 sandpaper

Came up smooth as

Permatex ultra-copper RTV seems to be pretty awesome for those types of applications too.

Fixed, kind of. Have an exhaust leak at the back of the turbo, v bands and I have a bit of a love/hate relationship, something has moved slightly and now the v band flanges have a bit of a gap along one side.

I've warmed it up and moved things around so I'll try retightening it when it cools down, if that doesn't work I'll buy a flexi and install that, it should probably have one anyway to help stop the manifold cracking.

Other than that it all seems okay, the manifold gets very hot very quickly, seems to sound a bit better to my ears as well.

Bought the most expensive flexi in the world this morning but the down pipe is done and on the car. Took it for a test drive and it's going pretty well, not as fast as it was before as it's only running wastegate spring pressure which I think is about 7 pounds, I need to get the banjo fittings for the wastegate back off the Z before I can hook up the boost controller, I'll try and do that this week.

Sounds a little bit different, the wastegate sounds quite funny.

After some discussion with Zac I'm leaning towards putting the Link out of the Z into this rather than trying the SR computer, might have a chat with NZEFI and see what they think about using an SR computer with individual throttles, it should be doable as that's how GTI-Rs run factory.

Sweeeeeeeet

Niccceeee!

[DJZ]

Went and took the banjos for the wastegate, the MTX-L wideband gauge and sensor and the G4 out of the Z today. Will replumb the wastegate and boost controller tomorrow and try and get it back to running a bar of boost.

Was showing Zac about how I'd have to swap the chopper wheel in my spare dizzy for use with the Link when we realised that the factory chopper wheel would actually work. I've found an L20 computer to steal the plug out of to make an adaptor from the G4 to the original wiring loom if I definitely end up going that way. Would have to add in extra wiring for wasted spark but that shouldn't be too hard.
